To all whom 'it may concern:

Be it known that l, JOHN Aus'riu. a citi- Zen ol the United States, and a resident oi Newark, in the Count.)Y ol lisser; and Saie of New Jersey, have invented Certain new and useful Improvements in Windows, of whieh'the following is a specification.

The objects of this inrention are to pro Vide a window in whiiif` no sash cords or weights are necessary; to enable the sashes to be opened to the inaxiinuin capaeity of lche window.; to render both surfaces of the sashes accessible from inside the window, for cleaning and the like; to secure a tight impervious joint around 'the margins of the sashes when closed and thus all'ord complete protection from drafts and s'orins; lo look the said sashes iirmly and positively in closed posit-ion along their entire margins; to enable the sashes io he opened and lei'ft stationary at any desired point; to secure e simple efficient construction of window v which shall be durable and not likely io get out of order, and to obtain other adaf'antages and results as may he brought our in ihe following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each oi? ihe several figures, Figure l nn elevation of my iinproved window from the inside.y showing it in closed position; Fig. Q`is a` rerioal section of the window taken on line a', Fig. l, and looking' at 'the edge of the sashes or in the direction indicated hy the arrow; .if irl is a horizontal section through the pivot of the upper sash of the window, takenwon line j1/, Fig. 5, and showing the lockingfbar in unlocked position; Fig. 4 isan elevation of my improved window with the head piece removed and the looking bars in section. showing theright-hand half oli the window with the locking bar withdrawn in unlocked relation to the sashes and said s" shes ai; an angle as in Fig. 5, while he lei hand half of the window is shown in closed posii'ion with the locking, har in locking relation to the sashes;Fi 5 is a Yeriieal seeiion, look'- ing edgewise at the sashos and showin them swung into partially open position; Fig. (S is a View similar to Fig. 5, hut shijn'ving; the upper and lower sashes oi the wiudi'm"swung farther open, so 'chat the lower sar-1h is drawn ifarther up within the window i saine hy Joe operation of the turning oi lfhe upper upon its pivot; '7 is :i dciaii side View ya central vertical transverse of he sliding pivot of ihe lower sash, and Fis'. f minpper end View or 'i' an oi' :he

ln said drawings. l inifiicaies the :ironie of a window oifiuy iinll'iroved eonsruciion, said iframe eonilu'ising` opjioste 'vianihs f2, head sill il. outer easingn ing C. Upper and lower sash: "i respeelively, are shown moaned in seid iframe, and hin'e' together at their meet- :`\.\L ing ends, as ai. Q, 9, :5.o bend outward, said sashes normally ,lying in ille same vertical plane. v

The npp er sash 'Y is pivoi'ed nl; iis opposite edges by means pins l0, 10,which project into the grooves l2, l2 of slotted strips 11, ll .mounted upon the janihs 2, 2 of the window in lined vertical position. The said strips by their grooves 12 thus provide slidewuys for the sasn pivots 10, l0 and preferably said pivots have headed ex l'reniities ifi lying: in the laterally eiilarged portion oi the slide'wfays to prevent escape.

Below the no1-nml location oi. the pivots l0, i0? which enables the upper .sash to he erung inio closed position, as slmwn in hi? G. the slot oi the sirio 'il is oiI new rimer widih, as aL- lfl, so as in liniii; dow ward xnovenieni. oi' the .said pivots l0, l0, lo the said posiiion.' whiio @nai-ling iheni to he slid freely upward io ihe li-.

'indem The lower sash S is el ai ils opposiie edges with .sere which gnojef" 'nio ine groows npon which eraser also within the said grooves and adapted to l, joints heJween the opposite edges of the slide therein without ar'leoting the pivotal .or swinging action of the sash. Each shoe lll-is ''sliaped in plan, as shown in Fig. S, to it the groove 14 and is elongated lengthwise or" the said groove as shown in Fig. 7 furthermore, the hole 17 in said shoe to receive the screw 15 of the sash has its lower wall beveled downwardly' toward the sash, as at 18 in Fig. 7 whereby the shoe is enabled to move out of parallel relation to the sash and cramp or bind against thebottom of the groove and the opposite walls of the undercut portion of the same. This cramping action occurs only when the sash is allowed to drop or fall downward with considerable velocity, and thus serves automatically as brake to arrest such undue .velocity of movement.

l have shown the upper sash pivoted at or near the middle ot' its opposite edges and the lower sash pivoted near its lower end, but obviously this relative arrangement ofpivots could be exactly reversed if desired, or the pivots otherwi e disposed with relation to each other.

lt will he understood th at when the upper and lower sashes are closed they lie in the same verticalplane, forming at their oppo site edges joints with the slotted strips 11, 11, which must necessarily be more or less loose and open to permit swinging of the sashes with freedom, and an important feature or" my invention consists in the means which l have provided for imperviously closing this joint when the window is shut and loclring the sashes in closed position. These means will next be described.

Adjacent to the slotted strips 11, 11, the jambe 2, 2 of the window frame are each longitudinally slotted, as at 20 'in Figs. 3 and 11 inoreparticularly, each of the said grooves having on its bottom an outwardly projecting median tongue 2l. il locking' bar 22 is adapted to lie in each of said grooves 20, being itself grooved at its inner edge as at 23 to receive the said tongue 21, and said locking bar when in its inner position in the groove 20 of the jamb clears the joint between the adjacent slotted strip 11 and edges of the sashes, shown in full lines in Fig. 3. ln the edge oit the. tongue 21 are formed downwardly and outwardly (with respect to groove) beveled notches or inclines 24, and on the bottom oli the groove 23 of the locking bar are correspondingly beveled projections 25 which when the locking bar is seated as shown in Fig. 3 fit into the notches 2l and present no obstacle to such proceedinff. lDownward sliding of the locking bars, however, would obviously cause the inclined projections 25 to engage the inclines 24, and torce the two locking bars at yopposite sides of the window toward each other to overlapcand cover the open sashes and slotted strips 1l, l1, as indicated by dotted lines in Eigt 3 and shown full in' section at the left hand side or Fig. 4. The said locking bars 22, 22, project at their lower ends through the sill il, and at their upper ends through the head 3, of the window, as at 26 and 27 respectively. The walls oig said .opening 26, 26 in the sill, which are next to each other, are beveled downwardly inward or away from the window frame as at 2S, 28, and these beveled surfaces are adapted to engage coperating surfaces 29, 29 on the locking bars 'which are beveled upwardly and toward the window frame. Similarly the openings 27, 27, in the head 3 of the window have adjacent beveled walls 30, BO, inclined downwardly away from the window frame, which are adapted to engage bevels 31, 31 on the locking strips which are inclined upwardly toward the sides of the window trame, as clearly shown in Fig. 4.

'lhe sets of bevels at the inner or exposed edges of the lockingbars, just described, are so located with respect to the other sets of bevels above described on the bottoms oit' said bars and their grooves, as that when the former are in engagement the latter are out of engagement. ln other words, the bevels 24, 25 at the bottom of one of the locking bar grooves 20, serve to throw said har into locking relation with respect to the sashes when it is moved downward, and also into such position that a reverse upward movement of the bar will cause its bevels or iuclines 29 and 3l to engage those on the sill and head to shift the locking bar back again into its groove 20 and clear or expose the joints between the sash edges and strip 11 again. Longitudinal movement of the locking strips thus serves to shift them horizontally tocover and uncover the joints at the edges of the sashes. This longitudinal movement of the locking bars is effected by means of a head-piece 32 arranged at the top ot the window at the inside thereof, and slot-tod as at 33 to receive studs 34 on which it may slide vertically. 'lhe ends of this hea-d piece 252 are connected to thc upper ends of the locking hars in any suitable manner that will cause the locking bars to move ver-4 tically with the head piece while permitting their independent movement ina horizontall direction. lu the drawings, particularly l*`igs. 9 and l0 thereof, l have shown thc head piece 32 provided at its lower edge with a rib 35 which enters transverse recesses or slots 36 in the upper ends of the looking bars, but obviously any other equivalent connection may be ei'nployed. The said head piece is provided with means 37' for receiving the hook ot a window pole, to slide the head piece up and down, and it will be noted that the head piece itsell overlaps in einem its lowest position the upper edge of the top sash, so as to close the joint made thereby with the head of the window. f

I do not wish to be understood as contining myself to the particular construction of inclines above described for obtaining the opening and closing horizontal movement of the locking strips, since other forms embodying the same princi; le may be employed equally well, as for example the one shown in Fig. 12. 4Here 38 indicates a locking bar which is provided with transverse slots 39 which are oblique or inclined with respect to the length of the lockingbar, and adapted to receive fixed pins (not shown) on the window frame. @bviously longitudinal movement of such locking bars as these would cause also lateral shifting of thc bar such as has been above described.

In order to secure a tight joint of the lower edge of the bottom sash with the sill of the window, corresponding to those which I have described at the sides and top ot' the window, I have shown the bottom rail 10 of the lower sash longitudinally slotted or grooved at its lower edge and provided with a strip 41 slidably mounted in said groove and ada ted to be pushed downward when the win ow is closed, by means of a finger piece 42 projecting through the top of the rail, to enter a corresponding groove or recess 43 in the sill.

Obviously, instead of using a single locking bar at the inside ot' the edge of the sashes, as I have described, two such locking 'strips might be employed, one on the outside and the other on the inside. In Fig. 13 I have illustrated such a construction, 45 indicating a sash with its pivot 46 sliding in a strip 47 mounted on the jamb of the window frame. (')n both sides of the said strip 47 are shown locking Tears 49, 50, each havinga tongue 51 (or 52) which slides between a piece of molding Fill (or and a fixed strip 56 (or 5T) upon which may be formed the bevels or inclines to engage those on the lockingbar, none of said bevels or inclines being shown in Fig. 13, which is a cross-sectional View, -but their construction has been already above described.

My improved locking bars enable sashes hinged as l have shown and described to be employed and still the window be .made tight and iniper.'ious to cold and inclement weather. The advantages ot' the sash construction are that there are no weights, cords or pulleys, the window frame occupies less space, and the sasbes can be opened to the full capacity of the window, as well as to render both their surfaces accessible Jf'or cleaning or the like. At the same time, the ent-ire construction is simple, durable, easy to operate, and not liable to `et out of order.

The hinges i) which connect the upper and lower sashes 7 and S are preferably provided with removable hinge pins 9'1,"which can be withdrawn when desired and the two sashes enabled to swing and otherwise act ear-h independently ot' the other. This enables one. halt of the window to remain closed while the other half is opened more or less, as desired. lfnrthermore, when the sashes have been brought to any desired open or angular position, they may be bound or locked `in such position with considerable firmness and rigidity by operatingA the locking` bars as it' to close them over the edges ot' the sashes when completely closed. engage the edges ot' the sashes and Ybind the latter in their position to hohl them against inadvertent displacement.

llavinp` thus described the invention, what l claim as new is.

l. In a window, the combination of sashes normally lying; in the same plane and hinged together at their meeting end edges, pivots at the side edges of said sashes, the pivots of one sash being located intermediate oi' the ends thereof, a frame providing slide'ways forl said pivots, and `means for holding" said sashes in any posit-ion.

2. ln a window, the combination of' a 'frame having at its opposite jambs slideways which are wider for theirupper portion than at the lower part of the window, sashes normally lyingr in the same plane and hinged together at their meeting edges, pivots projecting:r from the said sashes into the said slideways, the pivots on the upper sash entering the larger portion of the slide ways and being too wide to enter the lower narrower portion, and means for locking said sashes.

3. vln a window, the combination of a window frame, a sash pivoted at its side edges and intermediate ot' its ends in said frame and adapted to swing out of the plane ot' the frame, locking bars at the inner sides ot' said window frame adapted to move in a` direction perpemlicular to said inner sides, and means for operating said locking bars at both edges of the sash simultaneously.
